When a spin pays nothing and exactly two scatters are showing, the fifth reel alone spins one more time, in search of a third scatter or a paying line.
The fifth reel goes round again
Eddy landings give a near miss one more look. The first four reels stay exactly where they stopped while the fifth reel turns again on its own.
The new fifth reel may finish a line, bring the third scatter that opens free spins, or miss altogether. Each spin can have only one eddy, and it uses no extra credits.
A worked example. Scatters sit on reels two and four and no line pays. Reel five spins again, and a scatter landing there starts the free spins.
